While it may be 3d-printed, this device isn't quite in the realm of DIY yet thanks to needing some kinda-exotic metal oxide framework (MOF) materials.

Yep, I think the "cleverness" here is that it isn't fully passive strictly speaking, it requires some human input on a regular basis to meet the posted numbers. Namely, you have to open and close the little chamber at the correct interval, and squeegee the water into the collection material every so often with that French press-like thing on the top.

It ain't making 1.6 gallons of water a day with that little chamber no matter how much "free human labor" you add.

The internet is full of this free water bullshit. Maybe they could power it with a perpetual motion machine.

Thunderfoot has been outing this for years.
